` Application ined Aprii 5, 1922. semi No. 549,740.Y

1/"0 all whom t may concern Beit known that I, WILLIAM O.4 LLEWEL- LYN, a citizen of the United States, residing at vWilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented` certain new and useful Improvements in` 'y 'Automatic Blocks land Deadlatches; and I do hereby declare the following to be a full, clear,` and exact description of the invention,

such as will 'enable others skilled in the artv `mine railroads where it is desirous to pron vide a safety device for preventing runaway cars where' such cars in numbers are stacked awaiting their turn for `entering the mine shaft to be loaded, and has vfor its primary object the provision of a head block and a derailer so'located with respect to each other that in case of a car getting by the head blocln'said car will shortly thereafter be derailedj and preventedl from doing serious damages.

Another object of this invention is vthe provision of an operating means for posi-' tioning the head block and derailer to permit the passing of cars when desired and which when released will permit the head block and derailer to assume their operative positions. y

Another object of this inventionis the provision of an automatic block and dead f lock of the above stated character which For a complete understanding of my in vention, reference is to be had to the following description and accompanying drawings, in which:

Figurev 1 is a side elevation, illustrating an automatic safety `block and dead lock arranged on an inclined track and preventing a car from running away.

Figure 2 is a top plan view, illustrating the saine,

Figure 3 is `an enlarged detail view, illusf ti'ating the operating means, i Figure 4 is a transverse sectional view, illustrating the device.l

Referring in detail' to the drawings, theI numeral 1 indicates a mine railroad track and on which cars are adapted to be stacked to-V await their turn to enter the mine shaft for loading and it is now compulsoryby law to provide a safety device for preventing such cars, while stacked on an incline, from running away. To comply, with the law and to prevent property damage, I have provided an automatic safety block andfdeadila-tch 2 comprising a head block 3 of elongated forn mation which is pivotally supported at one i end as shown at 1, while its other rend is cut away to form an extension or shoulder `5 adapted to overlie one of the rails 6 of the track 1 for the purpose of engaging one of same. A link 7 isv connected to the blockB adjacent its free end vand toa pivotally mounted bell crank lever 8 which is in turn connected to a pivotally mounted operating lever 9 so that said block maybe swung on its pivot towards and from the'rail 6 when desired. i I f Located adjacent to the head block and in the otherv rail '6 of the track is a dead latch 10 comprising a rail section 11 provided with a cut out portion 12 and said rail section has its end laterally curved, as shown at 13, toy cause orv direct the wheels of a car off of the rails 6. v A closing latch 14 is pivotally mounted, as shown at 15,

and when in one position is adapted to4 form a continuation or a closureto the rail section so that the wheels of a car may pass over the derailer onsaid rail section without being thrown off of the track. A spring housing 16 is located adjacent the frog and has located therein a tension spring 18 that is secured to a rod 19'which is in turn connected to the latch 14 forthe purpose of positioning` the same to open'the rail section and permit the derailing of a car.

the wheels of a car to act as a chock for the A rod 20 is connected to the pivoted end l of the head bloc-k and to the free end of the latch for the purpose of moving the latch into a closed position simultaneously with the movement of the head block into a position away from the other rail of thev taining;` such momentum that it would do serious damage when derailed While l lave shown and 'le preferred embodiment of my will be understood that m i and of parts may he Without m from the spirit and scope oit the invention as claimed.

Having thus What l claim is:

l. ln combination with a railroad track, a head block adapted When in one position to form a chock, a derailer for said track described my invention and located adjacent to the block, and

manually actuated means :for po" tioning;v the derailer in a closed position and vmultaneously positioning the block .laterally of f ler thetrack and adapted to return the d i to an open position and the block into its lirst position when manually released.

2. A device of the character set forth including a railroad track,A a pivotally mounted head block adapted when in one position to overlie one of the rails oit the track to act as a chock for a car Wheel, a derailer lor said track and located adjacent the block, means normally holding` the derailer in an open position and the' block in said position, and means for closing the derailer and simultaneously moving the block laterally ofthe track.'

3. ln combination with a railroad track, ay pivotally `mounted block adapted when in one position tooverlie one of the rails or" the track to iorm a chock, a derailer in said track adjacent ,tov the lolock, means connecting the derailer to the block, tension means connected to the derailer for normally iolding the saine in an open position andto hold` the block in said lirst position., and an operating medium cony nected to the block :tor positioning the saine laterally of the track and to close the derailer. o i

vin a combination with va railroad track, a pivotally mounted block having` one end positioned over one of the rails of thel track `when in one position, a derailer in thetrack and located adjacent tothe block, a bar connectingY the block and derailer, tension means connectedito the derailer for normally holding the saine in an open position and to place the` block end in' said first position, a link connected to the block, a pivotally mounted hell crank lever connected to said link, and an operating medium connected to said bell crank lever 'for closing the derailer and for positioning); the block laterally of the rail of the track.
